Vacuum Pump (Oil Rotary Vacuum Pump) Oil-sealed Rotary Vacuum Pump Components Division, ULVAC, Inc. Vacuum Pump The PVD series belt-drive oil rotary vane pumps are compact, quiet running and robust. The superior pumping performance of these industrial strength pumps has earned them an excellent reputation among many users. Applications • Vacuum drying and freeze drying • Vacuum packing, vacuum adsorption and transport • Gas substitution, filling and vacuum heat insulation • Vacuum casting, etc. VACUUM COMPONENTS Pumping Speed Curves L/min m3/h 500 30 400 Pumping Speed • Consistent Pumping Performance The pumping performance of the pump is extremely stable. • Low Vibration and Low Noise The pump is suitable for use in noise and vibration sensitive environments. • Easy Maintenance Because the pump body is machined from a single aluminum block casting the unit has fewer parts to maintain. • Gas-Ballast Valve Gas ballast valve is standard with these pumps to effectively deal with water vapor from condensation. • Oil-backflow Prevention This model contains an oil-backflow prevention device as standard equipment. • Various Options An optional base with casters allows ease of movement of the pump. Pumping Speed (JIS B8316/1985) Type : PVD-180(B),PVD-360(B) Power : 50/60Hz AC200V 3φ Oil : ULVOIL R-7 Gauge: Pirani Gauge CCM Gauge Gas ballast closed Gas ballast opened
